liquid-phase sintered silicon carbide is 1250oC, i.e., its strength will not decline below 1250oC. Performance characteristics: high hardness (> 2100), high strength (> 650Mpa), small density (3.24g/cm3), lower cost of production than pressureless sintered silicon carbide products, suitable for mass production. Suitable for: workpieces with general requirements on abrasion resistance but high requirements on bending strength and resistance to shock such as gasket rings of large-size machines for rinsing conditions, hard panels for lightweight ballistic armor, lightweight wear parts with complex shapes and forces etc.
